MACHINE FOR DlSINTEGRATlNG RAMlE AND OTHER FIBROUS MATERIALS.

SPECIFICATION forming part of Letters Patent No. 440,775, dated November18, 1890.

Application filed October 2, 1889.

To all whom it may concern:

Be it known that I, EDMOND MARC, architect, a citizen of the Republic ofFrance, at present residing in the city of Paris, France, have inventedcertain new and useful Tmprovements in Machines for Disintegrating Ramieand other Fibrous Materials; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters and figures of reference marked thereon, which form a part ofthis specification.

Referring to the drawings, Figure 1 is a side elevation of the lowerpart of a machine embodying my invention. Fig. 2 is a plan View ofFig. 1. Fig. 3 is a front end elevation of the entire machine. Fig. 4 isa sectional side elevation of the upper portion of the machine. Fig. 5is a top plan view of Fig. l. Fig. 6 is a sectional front end elevationof the upper part of the machine, and Fig. 7 is a detail view of one ofthe clamps.

The invention relates to the art of preparing the ramie or rhea andother like fibrous materials for spinning; and it has for its object toprovide a machine in which the operations of preparing the fiber areperformed automatically.

The machine is designed more especially for disintegrating the fibrousmaterial after it has gone through the process of breaking ordecortication to remove the gummy or resinous matter that unites thefibers; and it consists in operating devices comprisingelectrically-controlled rubbing-surfaces, said surfaces being adjustablerelatively to the length of material operated upon; in means forimparting to the material a reciprocating mo tion between therubbing-surfaces, in combination with reversing-gear operating auto-'matically to reverse the motion of the material; and in the combination,with the mechanism for imparting a reciprocating motion to the materialoperated upon and with the rubbing-surfaces, of electrical devicescontrolled by and timed to the movement of the said material, wherebythe rubbing-surfaces are moved out of contact with the material duringits motion in one direction.

mechanism, of which S is the main drivingshaft. I would here observethat this main driving-shaft has a continuous motion and is driven fromany suitable prime motor, and carries, besides the pulley P, driven fromsaid prime motor, two pulleys P and P belted to corresponding pulleys p10 on a countershaft Sthat is to say, the pulley P on shaft S is beltedby means of a crossed belt B to pulley p, and pulley P on said shaft Sis belted by means of a straight belt B to a pulley p on saidcounter-shaft S. By the side of each pulley p p on shaft S is mounted aloose pulley 19 19 respectively, to which the belts B B areautomatically shifted to reverse the rotation of shaft S. This iseffected as follows: One end of shaft S is screw-threaded, as shown ats, and carries a nut N, that is held against rotation with the shaft byguideways G G, along which said nut is free to slide, so that as theshaft S revolves the nut N is moved longitudinally thereof along theguideways G G. The nut N has a tappet n in the path of two abutments rand r on a belt-shifting rod R, that has two shifting-forks r rstraddling the belts B B respectively. The abutment r on rod R isadjustable by means of a set bolt or screw 1, Fig. 2, so that thedistance traveled by the nut may be adjusted or regulated. Thecounter-shaft S carries another pulley P belted by means of a straightbelt B to a pulley p on a second counter-shaft S at the rear end of themachine, and by the side of said pulley P is arranged a loose pulley 10The counter-shaft S also carries a cord-drum D, on which is wound a cord0 that has one of its ends fixed to said drum and passes around a guidepulley or drum D at the front end of the machine, said cord having atthat end a clamp C, Fig. 1, attached for holding one end of the fibrousmaterial and to be hereinafter described.

The belt B is shifted from the fast to the loose pulley on shaft S bymeans of a hand shifter-rod R, that has the belt-fork "r and that slidesfreely in bearings b b the fork of the shifting-rod operating on thelower part of the belt.

The motion of the pulley p can be arrested independently of thebelt-shifting devices by means of a brake, consisting of a brake-shoe b,Fig. 1, connected by means of a link I to a bell-crank lever L, pivotedat Z on a suitable bracket 1), Figs. 1 and 2, said bell-crank lever Lbeing connected with an operating-rod R The operation of these devicesis as follows: It being presumed that belt B is on its loose nulley 19motion being imparted to the shaft S in the direction of arrow m Fig.2,the counter-shafts S S are revolved from right to left, as shown byarrow 00, Fig. 2, through the medium of belts B B thereby unwinding thecord C from drum D. As shaft S revolves, the nut N travels outwardly,and when tappet 7 contacts with abutment r the rod R is moved in thesame direction, thereby shifting belt B from fast pulley 1) to loosepulley p and belt B from loose pulley p onto fast pulley 19 thusreversing the motions of the shafts S S the cord being wound on drum D.

Having described the arrangement and operation of the main drivingmechanism and shown that a motion in one direction is imparted to thecord 0 to draw. the material operated upon in a like direction, one endof said material being clamped in clamp (3, Fig. 1, also that the cordis unwound from drum D to permit its being drawn in a reverse direction,and that this alternate movement of the cord and drum D is effected bythe automatic reversal of the rotation of shafts S and I will nowdescribe the means for drawing the material in a reverse direction fromthat described, as well as the means employed for freeing such materialfrom the gummy constituents, to place the fibers in a condition forspinning, reference being had to Figs. 4, 5, and 6. The superstructureof the machine consists of an open frame F of rectangular form, boltedor otherwise secured to suitable uprights on main fgame F. To each ofthe longitudinal girts f DI frame F is secured a rail E, the tread ofwhich is preferably rounded off, (see Fig. 6,) one of said longitudinalgirts' being provided with an upwardly-projecting flange f whose treadis also rounded, as shown in said Fig. 6. At the front and rear ends ofthe machine the rails E are connected by cross-girts e 6, respectively,and in the rear cross-girt e is formed an opening 6 a similar openingbeing formed in a lug f projecting from the front cross girt f of frameF. (See Fig. 4.) A rod R arranged centrally of the frame F, is supportedand slides freely in said openings. The rod R has at itsfront and rearends stop-collars r and 4", respectively, and near its front end anadjustable abutment 1 (see Fig. 4,) and to the abutment r is secured ametallic contact M O, for purposes presently explained. The

adjustment of the abutment r may be effected in any desired manner, asby means of a setscrew 7', Fig. 4.

On the rails E rests a four-wheeled carriage G, the body of which isrectangular, and preferably a sheet-metal box, divided into four (moreor less) compartments 9 by cross-partitions g, so as to form receptaclesfor ballast, such ballast consisting of any weighty substance,preferably shot, so that the stability of the carriage on the rails maynot only be insured, but the weight of said carriage varied, to vary thetension of the material operated upon, as will hereinafter appear. Thecarriage G at its rear end has attached to it a cord 0 that passes overa guide-pulley 0 and has attached thereto a counter-weight W. (See Fig.4.) To the front end of the carriage is hooked a clamp C, similar to theclamp O, hooked to cord 0 for holding the other end of the material. Theclamps are each constructed as follows, referring to Fig.7. Upon a plate0, that has longitudinal corrugations so as to form more or less sharpteeth, are hinged a number of blocks 0, that have bosses 0 provided witha perforation 0 that is preferably rectangularin cross-section,one halfof the perforation being formed in the boss and the other half in theblock, though this is not absolutely necessary, as the perfo ration maybe formed in the bosses solely. At each end of the plate cis secured orcasta block 0 also provided with a similar perforation. 0 is a lockingpin or bar,that has the same form in cross-section as the blocks andbosses referred to, and by means of which the hinged blocks 0 are firmlylocked to plate 0. The material is secured by inserting one end of abunch between the plate and first block a of the series, spreading itout properly, then closing the block upon the material and pushing thelocking-rod into the same. In a similar waya bunch of material is spreadon the plate 0 under the second block, and so on until finally thelocking-bar is pushed into the stationary block 0 at the opposite end.The blocks 0 are corrugated or toothed transversely, so that when lockedto the longitudinally-corrugated or toothed plate 0 the end of thematerial is firmly held between the two.

In Fig. 7 I have shown one of the blocks turned up, the boss 0 beingpartly brokenaway to show the handle 0 of the clamp on which is formedthe eye 0 by means of which it is hooked either to the cord C or tocarriage G. At the front end of the frame F is mounted a guide-drum Dover which the material travels during its movements to and fro.

From what has been said it will be readily understood that the materialheld in clamps O O is moved from left to right by drum D and cord 0 andin a reverse direction by weight W, attached to cord 0 and carriage G.It will further be obvious that by varying the load in carriage G thetension upon the material held between clamps O and O can be varied.This may also be effected by using a plurality of weights, as shownindotted lines in Fig. 4, adapted'to be removed and replaced at will.

To the front end of the carriage G is secured an arm g that has a forkedend g straddling the rod R and on the under side of said carriage G atthe rear end projects a fork 9 that also straddles the rod R (See Fig.4.) The fork g operates on the adjustable stop or abutment 7' and thefork g on the stop-collar r, for purposes presently explained.

On the rails E and flange f is seated a scraper-frame H, that has aprojection h, in which is formed a vertical groove for the reception ofthe end of a bracket or shelf K, that is adjustable vertically in thegroove by means of a screw it, for purposes hereinafter explained. Thescrew 70 worksin a threaded opening in said bracket K and revolves insuitable bearings h h, the screw being operated by the lever-handle L.From the frame H projectsa standard h that is preferably square incross-section, and on said standard slides freely asl'eeve 0, connectedwith or having formed thereon a plate to which is hinged a secondscraper-frame O, that is adapted to move vertically with the sleeve 0,as presently explained, and is moved back into its normal position afterhaving been depressed by a spring h arranged on the standard 72. betweenthe sleeve and the lower scraper-frame H.

The object of hinging the frame 0 to plate 0 is to afford better accessto the scraper-bars, as the frame may be swung up, as shown in dottedlines in Fig. 6, when it is desired to remove and replace suchscraper-bars.

To prevent the frame 0 from swinging on its hinges, I provide twoperforated bars 0 0 through which passes a locking-bar 0 that takes intoa hole in the sleeve 0 and is secured against displacement by aset-screw 0 The frame H is secured against motion on the rails E andflange f 2 by means of binding-screws h", Figs. 4 and 6, or any otherdesired means. The said frame H has, as shown,

six scraper bars or ribs H, the upper frame having but five scraper-barsO and so arranged relatively to the bars H as to lie in a planeintersecting the space between each two bars H, as shown in Fig. 4.

The scraper-bars are constructed of hard wood-such as Guat'cum(lignum-vitae) or other like wood or of ivory-an-d have atolerably-sharp cutting or scraping edge, not sharp enough, however, tocut the fiber. The scrapers are secured to bars of metal or wood It 0respectively, that have perforated lugs through which passes a pin 71 or0 by means of which they are secured to their respective frames H 0. Tothe rear face of frame H is secured a buifer H Figs. 4 and 5, to deadenthe shock of carriage G and prevent injury to the electric contactspresently to be described.

Upon the under side of the scraper-frame H are secured threebinding-posts 1, 2, and 3, respectively. The binding-post l is connectedwith one of the line-wires wand the binding-postf3 with the otherline-wire v.0 and to said binding-post 1 is secured a metallic contact MO in the path of the contact M O and in connection with line-wire w. Thebinding-post 2 is connected by wire to with contact M O, and said post 2is also connected with binding-post 3, and consequently with line-wire10 The binding-posts 1 and 3 are respectively connected withbinding-posts4 and 5, to which the terminals 10 and w of anelectro-magnet E M are connected. (See Fig. 5.) The wires are connectedto the opposite poles of an electric battery composed, preferably, offour Leclanch cells contained in a wooden box W B. (See Fig. 3.)

In some cases where the adjustment of the scraper-frames on the rails Eand flange f varies considerabythat is, if fibrous materials the lengthof which varies considerably are treated-the box W B may be supportedfrom the frame H, so as to avoid using wires w 10 of such a length as torender them liable tobecome entangled in the belting or the cord 0below. A circuit-breaker O C is connected with the box, so that thecircuit through the electro-magnet E M may be interrupted by handwhenever desired.

A is the armature of the electro-magnet E M, and A L the armature-leverwhose outer end is forked, the branches of the fork terminating intoothed sectors T S, that mesh with rack-bars R B, secured to oppositesides of the sleeve 0 on standard 7L2. The upward movement of thearmature-lever A L is limited by a bridge B, as shown in Figs. 5 and 6.

To the scraper-frame O are secured brackets or bracket-arms 0, that haveopenings through which pass vertical rods 0 that have bearings forrollers 0 and 0 respectively, on opposite sides of the frame 0, (seeFigs. 4 and 5,) said rods 0 being adjustable in their brackets by meansof set-screws 0 These rollers serve to hold the material down againstthe first and last scraper-bar of frame H, as shown in Fig. 4.

The operation of the last-described mechanism is as follows: Supposing aclamp full of fibrous material operated upon has just been removed, thebrake b being applied to pulley B to stop the motion of shaft S and afresh clamp full of material in position, the carriage G being in theposition shown in Fig. 5, on reaching which position the fork 9 comingin contact with stop 0", draws back the rod R thereby closing thebattery-circuit by the contact of M O with M C. The closure of theelectric circuit will attract the armature A and armature-lever A L,thereby depressing the upper scraper-frame 0 into the position shown inFig. 4 through the medium of the toothed segments T S and rackbars R B.The pulley B being released from the brake Z), the cord 0 will draw thecarriage from left to right, the material passing between thescraper-bars H 0. As the carriage approaches the right end of themachine,

the fork g carries the contact 7* along, thereby interrupting thecircuit through the electromagnet E M, when the spring It will move theupper scraper-frame O upward, thereby causing the rollers 0 to releasethe material held in clamps C and O. This abutment r is so adjustedrelatively to the abutment r of the belt-shifting rod B, Fig. 1, thatthe closure of the electric circuit will take place a little before thereversal of the rotation of the shaft S. When this has taken place, thecord 0 will unwind from drum D, thus permitting the weight W to draw thecarriage G back to its starting-point, thereby again closing theelectric circuit. Simultaneously therewith, or nearly so, the arm 'n onnut N will contact with abutment r of belt-shifting rod R to shift thebelt B from the fast pulley p to the loose pulley p and the belt B fromthe loose pulley p to the fast pulley W, as shown in Fig. 2.

As the scraper-frames are adj ustable on the rails E and the flange fthey can be moved nearer to the left end of the machine, according tothe length of material to be operated upon. scraper-bars H O and therollers o 0 may also be varied by adjusting the shaft K, and through themedium of the toothed segments T S the scraper-frame H on standard h bymeans of screw 70, hereinbefore referred to. The degree of tension ofthe fibrous material while being operated upon may also be variedaccording to the nature of the said material by varying the weight ofcarriage G or that of weight W, attached to cord G It will be readilyobserved that the ma chine may be employed as a breaker for breakingfibrous materials, and that by simply substituting comb-plates for thescraper-bars the machine may be converted into a carding or combingmachine.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-
